A Frequency-Tracking and Impedance-Matching Combined System for Robust Wireless Power Transfer
International Journal of Antennas and Propagation, 2017 One of the greatest challenges to power embedded devices using magnetically coupled resonant wireless power transfer (WPT) system is that the amount of power delivered to the load is very sensitive to load impedance variations.

Impedance of rigid bodies in one-dimensional elastic collisions
, 2012 In this work we study the problem of one-dimensional elastic collisions of billiard balls, considered as rigid bodies, in a framework very different from the classical one presented in text books. Implementing the notion of impedance matching as a way to

Resolving Photon Numbers Using a Superconducting Nanowire with Impedance-Matching Taper.
Nano letters (Print), 2020 Time- and number-resolved photon detection is crucial for quantum information processing. Existing photon-number-resolving (PNR) detectors usually suffer from limited timing and dark-count performance or require complex fabrication and operation. Here we

Wideband strip antenna surrounding a ground plate
The Journal of Engineering, 2022 A wideband planar antenna, which is composed of a ground plate and a strip surrounding the plate, is proposed. Wideband impedance matching with fractional bandwidth over 130% is achieved by making the distance between the strip and the ground plate ...

Design of an underwater acoustic bend by pentamode metafluid
, 2017 We design an impedance matching underwater acoustic bend with pentamode microstructure. The proposed bend is assembled by pentamode lattice. The effective density and compressive mod- ulus of each unit cell can be tuned simultaneously, which are ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.
